Assumptions
- India tax logic is a simplified FY 2026-27 salaried-individual model.
- New-regime marginal relief is modeled in simplified form; surcharge, special-rate incomes, and state-specific details are not fully modeled.
- Verify current rules with a qualified tax advisor before filing or choosing a regime.

Taxable income = gross income - standard deduction - eligible deductions

What is Old vs New Tax Regime Calculator for Salaried Employees?
Old vs New Tax Regime Calculator for Salaried Employees answers a specific tax question without opening a spreadsheet. Enter annual gross salary and eligible old-regime deductions & exemptions, review the estimate as you type, and open the formula block to see how the result is produced.
It uses INR defaults, Indian number formatting, and India-specific assumptions where relevant.
Inputs explained
Eligible old-regime deductions & exemptions
The total you can actually claim under the old regime — deductions like 80C, 80D, home loan interest and NPS, plus exemptions like HRA. Leave out the standard deduction: the calculator applies that itself, and entering it here would count it twice. Supported range: 0 to 100,000,000.
Why it matters: This is what the old regime trades its higher rates for, so the comparison turns on it. The new regime allows almost none of it.
Count what you can evidence, not what you could claim in principle. MoneyThinker does not check your eligibility.
